ROTARY PLOW.

SPECIFICATION forming part of Letters Patent N 0. 463,047, datedNovember 10, 1891.

, Application filed August 27, 1891- Serial No. 403,887. (No model.)

plows in which a rotary disk-plow or cuttingwheel is mounted diagonallyto the line of draft at the rear'of a suitable frame that is adj ustableon its axle to vary the distance between said plow and an adjacentstaggered guidewheel by which the tendency to side draft, due -to thepressure of the soil against the plow, is

effectually prevented, while the soil thrown out by the plow is receivedon an unbroken or solid convex surface of the dished and staggeredguide-wheel and discharged at the rear, so as not to retard theoperation of the machine.

The invention consists in the construction, combination, and relativearrangement of parts in a rotary sulky-plow, as hereinafter more fullyset forth.

In the annexed drawings illustrating the invention, Figure 1 is aperspective of a ro tary sulky plow embodying my improvements. Fig. 2 isa partial plan of the machine. Fig. 3 is a rear view of the machine.Fig. 4 is a vertical section through the lifting mechanism of the rotaryplow, and Fig. 5 is a section through the rotary plow and its axle.

Referring to the drawings, the numeral 1 designates a draft-tongue,which is firmly secured to the forward ends of hounds 2, that constitutethe frame of the machine. About midway their length the hounds 2 areadjustably attached to a straight axle 3, by means of clips 4 passedbeneath the axle and through each hound, on the upper side of which theyare secured by washers 5 and nuts 6, so that by loosening said nuts theframe of the machine can be adjusted laterally on the axle to give therequired adjustment of the rotary plow toward or from the guidewhcelandthereby vary the widthof thefurrow, as here inafter explained. Thehounds '2 may each be provided with a longitudinal series of holes orvertical perforations 7 for passage of the screw-threaded ends of theclips 4., so that by inserting said clips in the foremost or rearmostholes, as required, the frame of the machine may be adjusted rearward orforward,

as desired.

To the under side of the rear ends of the hounds or frame-pieces 2 areattached adjustable obliquely-arranged journal-boxes 8 by means of clips9,,the upper screw-threaded ends of which are extended through holes orvertical perforations 10, formed in the hounds and secured by washers 11and nuts 12 on the upper sides thereof. In the boxes 8 are supportedrotary sleeves 13, through which is passed an obliquely-arranged bolt14, on which, at the inner side of the right-hand hound, is mounted adish-shaped rotary plow or cuttingwheel 15, with its concaved sideturned outward and forward. On the bolt 14, adjacent to the convex sideof the rotary plow 15, maybe placed an intermediate sleeve 16, and onone end of the said bolt is a nut rotary plow securely onto the bolt 14,which,

together with the sleeves 13 and 16, form an axle for said plow. Theseparate intermediate sleeve 16 may be dispensed with or made in onepiece with the adjacent sleeve. It will be seen that the left-handhoundis of greater length and is extended somewhat in rear of theright-hand hound, and also that the boxes 8, attached to the rear endsof said hounds, are placed obliquely, so that the rotary dished plow 15will occupy a position diagonal to the line of draft. By providing anumber of suitably-arranged vertical perforations 10 in the rear ends ofthe hounds 2 the clips9 and obliquely-arranged boxes 8 can be soadjusted as to vary the diagonal position of the plow to secure asuitable width of out.

On one end of the axle 3 is loosely mounted a land-wheel 18, which may,if preferred, be made dishing, as shown, for the purpose of obtainin gstrength and stability. To the other end of the axle 3 is securelybolted a vertical bracket 19, having on its inner side a horizon talsocket 20, in Which the end of said axle is received. The lower end ofthis bracket 19 is connected by a brace rod or bar 21 with the forwardend of the adjacent hound, thereby securing the said bracket against theeffects of strain. The outermost portion of the bracket 19 is in theform of a plate 22, which is engaged in vertical guides 23, that form asocket for said bracket 19 on the inner side of a casting or plate 24,the outerside of which is provided with a downwardlyuand outwardlyinclined boss 25, having a fixed'spindle 26, on which is loosely mounteda staggered an'd solid-dished wheel 27, thetire or rim of which runsagainst the inner edge of the last-made furrow and serves as a guide forthe rotary plow or'cutting-wheel in making the next adjacent furrow. .Itwill be observed that the concave side of the dished and staggeredguide-wheel 27 is turned downward and outward, while its convex side ispresented toward the concave side of the dished rotary plow 15, and itwill be further observed that by making the said guide-wheel 27 solid,as shown-that is, without spokes or ledges, but with a perfectlysmoothand unbroken convex surface-the soil thrown thereon by the rotary plowwill readily pass off at the rear of the machine without any liabilityof being carried forward to clog the operation of the wheel.

The upper segmental edge of the bracket plate 22 is formed with a rack28 for engagement of a pawl 29 on a hand-lever 30, that is pivoted tosaid bracket and formed with a lower rearwardly and upwardly curved end,

- which is connected by a link 31 with the sock eted guide-plate orcasting 245, on which the staggered and dished guide-wheel 27 iscarried. It is obvious that by this construction and arrangement ofparts the movement of the hand-lever 3O forward or backward will loweror raise the bracket-plate 22 in the guides 23 of the plate or casting24, and thereby lower or raise the hounds 2 and attached rotary plow 15,as the case may be. to vary' the depth of the furrow to be out. Bythrowing the hand'lever back until the pawl 29 comes against a ledge orstop 32 on the inner side of the bracket-plate 22 the rotary plow willbe raised entirely from the ground and remain inoperative while themachine is drawn from place to place.

The width of the furrows can be readily varied as required by adjustingthe hounds 2 laterally on the axle 3, as already mentioned, it beingonly necessary to loosen the nuts 6 on the clips 4 in order to shift theposition of the hounds so as to carry the attached rotary plow 15 towardthe guide-wheel 27,if it is desired to make a narrow furrow, or fromsaid wheel to make a wide furrow, and then tighten the nuts 6, asbefore, to secure the parts in proper relative position foraccomplishing the desired character of work. As before mentioned, thewidth of thecut or furrow made by the rotary plow 15 can also be variedby increasing or diminishing the obliquity of the boxes 8, which iseffected by removing the washers 11. and nuts 12 and changing theposition of the clips 9 in the perforations 10 to holdtheboxes 8 in therequired position. By

loosening the nuts 6 on the clips 4 and adj usting the hounds 2 forwardor back, the pos1- tion of the rotary dished plow 15 will be changed tobring it into more or less direct action with relation to the adjacentdished and solid staggered guide-wheel. By arranging this guide-wheel 27in proximity to the rotary plow or cutting-wheel 15 the tendency to sidedraft under the pressure exerted against the rotary plow will beentirely obvlated and the machine will be caused to move properly andlay the furrows evenly in the desired direction. The operation of theplow is also greatly facilitated by making the staggered guide-wheel 27in dishing form and with a solid unbroken convex surface presentedtoward the plow, so that the soil thrown onto said wheel will pass offfreely and rapidly to the rear and not hinder the working of themachine; tary plow and staggered guide-wheel having a solid convexsurface also permits dispensing with a colter or rudder in rear of theplow, as frequently required in other forms of construction.

What I claim as my invention is- 1. In a sulky-plow, the combination,with a rotary plow or cutting-wheel and its supporting-frame, of an axlehaving a land-wheel at one end and a staggered dished guidewheel mountedat the other end of said axle and having a solid and unbroken convexsur- This relative arrangement of roface in proximity to said plow toreceive the soil thrown onto it by the plow and discharge it at therear, substantially as described.
